The next step after adding CSS to highlight links with rel=nofollow is to give the user some information about what the symbol and the dashed line mean. Since CSS will not allow you to add tooltips and links, we have to resort to some javascript trickery. The up-side to this is that it will also display the markup on older browsers like IE 6. Adding this kind of markup to your site is pretty easy to do.

In the top right corner of this blog I have placed a small set of links that let you resize the text as it is displayed. It’s easy to use this script on your blog and it lets your visitors resize the text on the blog however they want it. The resizing setting is stored in a cookie, valid for one year, so when the visitor returns, they will see the site as they resized it last.
